For polarization-independent and low-crosstalk switching operation a Mach-Zehnder interferometer (MZI) type photonic switch using Multi-mode interference (MMI) couplers, an optimal structure was investigated. As a result, the combination of high-mesa and middle-mesa waveguides was found to realize low-crosstalk of -30 dB and polarization-independent semiconductor high-speed photonic switch.

The frame loss periods of the optical layer protection switching using PLZT optical switches, which can provide 10 ns order switching time, is evaluated. Experimental results show that 60 mus guard time after switching is required for 10 Gbps Ethernet which uses commercial available XFP modules.

To cope with a large intensity fluctuation of optical signals in optical networks, we expand the dynamic range of our proposed all-optical intensity equalizer by using effective self-phase modulation with pre-chirped signals. We have numerically confirmed a remarkable effect of proposed SPM alleviation method by pre-chirped signals for achieving a large dynamic range beyond those of the conventional SPM-based techniques.

For ASON/GMPLS multi-domain networks, three routing models, such as per-domain routing, ASON hierarchical routing, and PCE-based routing, have been being standardized. We compare these three routing models in terms of path-computation capabilities, online path-planning capabilities and inter-domain confidentiality.

A bidirectional WDM-PON exploiting reflective semiconductor amplifiers at the optical network unit (ONU) and a multiwavelength RZ pulsed signal comb at the Central Office (CO) is presented. The reflective SOA acts simultaneously as downstream modulation eraser, upstream amplifier and modulator, thus making the ONU wavelength-independent.
